Beautiful aquarium.

It would be helpful to know your exact water tests and results. In my experience, these issues are generally related to alkalinity and pH. It is also possible that your Yellow Tangs are dominating the new fish, especially at night after the lights go out.

Did I mention that your tank is awesome? Very nice.

i would also guess the two tangs are suspect. in the picture notice how the two swim together. they are actually shadowing eachother and this can stress the fish. i would keep an eye on it and do they show any aggresion towards eachother?

True.

I've also noticed with my Tangs that this behavior can also cause the fish to display aggressive behavior towards other species who come near this "school". My 180 is becoming an interesting lesson in Tang behavior!
